We store small text files called cookies on your computer so that you get the most out of the site and we can improve your experience for your next visit. If you continue exploring our site, we'll assume you're happy with this.
What is a cookie?
Put simply, cookies help a website to remember you. They’re small files of letters and numbers that a website transfers to a file on your computer or mobile device.
Without cookies, a website will always think you’re a new visitor every time you move to a new page on the site. Cookies make interacting with a website faster and easier.
Cookies also enable website owners to tailor the content to visitors’ needs. And they do all this without storing any information that can identify you personally.
|__utma||This cookie is typically written to the browser upon the first visit to the site from that web browser. If the cookie has been deleted by the browser operator, and the browser subsequently visits your site, a new __utma cookie is written with a different unique ID. This cookie is used to determine unique visitors to the site and it is updated with each page view. Additionally, this cookie is provided with a unique ID that Google Analytics uses to ensure both the validity and accessibility of the cookie as an extra security measure. |
|__utmb||This cookie is used to establish and continue a user session with the site. When a user views a page on the site, the Google Analytics code attempts to update this cookie. If it does not find the cookie, a new one is written and a new session is established. Each time a user visits a different page on the site, this cookie is updated to expire in 30 minutes, thus continuing a single session for as long as user activity continues within 30-minute intervals. This cookie expires when a user pauses on a page on the site for longer than 30 minutes. ||2 years from set/update|
|__utmc||This cookie is no longer used by the Google Analytics ga.js tracking code to determine session status. |
Historically, this cookie operated in conjunction with the __utmb cookie to determine whether or not to establish a new session for the user. For backwards compatibility purposes with sites still using the urchin.js tracking code, this cookie will continue to be written and will expire when the user exits the browser.
|At end of browser session|
|__utmz||This cookie stores the type of referral used by the visitor to reach the site, whether via a direct method, a referring link, a website search, or a campaign such as an ad or an email link. It is used to calculate search engine traffic, ad campaigns and page navigation within the site. The cookie is updated with each page view to the site. ||Not set|
|_intextra.web_session||A temporary cookie that applies to website administrator sessions only and expires at the end of the browser session.||At end of browser session|
